I have a website with a decent traffic. Since I am adding content on the website on a regular basis the traffic to the site is improving considerably. However the ecpm is not showing such improvements and is almost the same over a period. Does this improve with the age of the site.
I wish people who have no clue wouldn't respond. Your eCPM is earnings normalized so you can compare 1000 impressions. If you have 1200 impressions and make $6.89, doubling your impressions will not increase your eCPM unless the value per click or CTR etc increases.
